Gear Geometry 261

Gear Geometry provides an overview of the important design features of common gears. Involute gears have teeth that are shaped by an involute curve. In order to work properly, involute gears must meet precise geometrical specifications. Gear geometry includes tooth profile, pressure angle, pitch circle, clearance, and backlash. A gear's geometry significantly affects the way in which it meshes with another gear in order to transmit power and motion. The geometry of a gear affects its ability to function correctly and consistently transmit power throughout a mechanical system. Understanding a gear's geometrical features is essential to ensuring gears mesh together properly. After taking this class, a user will be able to describe the basic involute design of gears, its purpose, and define necessary terms for gear specifications.
